Put $100 with it and get a Reebok from Sam's if this spins your top. It is that much better of a treadmill than this one. Also, if all you have to spend is $599, go to Walmart and the Gold's Gym even stands above this one.
with inflation, the price has nearly doubled but the same crappy treadmill is at the heart of this deal. Look elsewhere in the Proform line if you have had a good history with Proform. Some of their new designs are much better and great looking to boot.
